BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘Sumnaricoaka’.

The new Verbena plant is a product of a planned breeding program conducted by the Inventors in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new compact, mounding and freely-branching Verbena cultivars with attractive flower coloration.

The new Verbena plant originated from a cross-pollination made by the Inventors in November, 2005 in Higashiomi, Shiga, Japan of a proprietary selection of Verbena hybrida identified as code number 00-17, not patented, as the female, or seed, parent with a proprietary selection of Verbena hybrida identified as code number 00-20, not patented, as the male, or pollen, parent. The new Verbena plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in October, 2006.

Asexual reproduction of the new Verbena plant by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since November, 2006 has shown that the unique features of this new Verbena plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Verbena have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunmaricoaka’. These characteristics in combination distinguish ‘Sunmaricoaka’ as a new and distinct cultivar of Verbena:

-   -   1. Compact and mounding to cascading plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Long flowering period.     -   6. Red-colored flowers that are held above and beyond the foliar         plane.     -   7. Good garden performance.

Plants of the new Verbena can be compared to plants of the female parent selection. Plants of the new Verbena differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Verbena are more compact than plants of the         female parent selection.     -   2. Plants of the new Verbena are not as upright as plants of the         female parent selection.     -   3. Plants of the new Verbena and the female parent selection         differ in flower color as plants of the female parent selection         have violet-colored flowers.

Plants of the new Verbena can be compared to plants of the male parent selection. Plants of the new Verbena differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Verbena are more compact than plants of the         male parent selection.     -   2. Plants of the new Verbena are not as upright as plants of the         male parent selection.     -   3. Plants of the new Verbena and the male parent selection         differ in flower color as plants of the male parent selection         have lavender-colored flowers.

Plants of the new Verbena can be compared to plants of Verbena ‘Sunmaricomu’, disclosed in U.S. Plant patent application Ser. No. 12/658,043. Plants of the new Verbena differ primarily from plants of ‘Sunmaricomu’ in flower color as plants of ‘Sunmaricomu’ have red purple-colored flowers.

Plants of the new Verbena can be compared to plants of Verbena ‘Sunvp-su’, disclosed in U.S. Plant Pat. No. 10,311. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Verbena differed primarily from plants of ‘Sunvp-su’ in the following characteristics:

-   -   1. Plants of the new Verbena were more compact than plants of         ‘Sunvp-su’.     -   2. Plants of the new Verbena were not as trailing as plants of         ‘Sunvp-su’.     -   3. Plants of the new Verbena flowered earlier than plants of         ‘Sunvp-su’.     -   4. Plants of the new Verbena had larger inflorescences and         flowers than plants of ‘Sunvp-su’.     -   5. Flowers of plants of the new Verbena had broader petals than         flowers of plants of ‘Sunvp-su’.
